"Be grateful for challenges because... Had there been no difficulties and no thorns in the way, then [each woman and] man would have been in his primitive state and no progress made in civilisation and mental culture."

Next Quote

We learn in the past, but we are not the result of that. We suffered in the past, loved in the past, cried and laughed in the past, but that's of no use to the present. The present has its challenges, its good and bad side. We can neither blame nor be grateful to the past for what is happening now. Each new experience of love has nothing whatsoever to do with past experiences. It's always new.
